Application filed July 25, 1914. Serial No. 853,112.

To all 'whom it may concern Be it known that I, JACOB J. lftnrAN', a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful improvements in Bottle- Closures, of which the following is a specifi cation.

rFhis invention relates to bottle closures consisting of a paper disk which is sprung into the bottle mouth, and being especially adapted for vmilk bottles.

lit is the object of the present invention to Y provide a closure of the kind stated which makes a hermetic seal and which is readily removable without danger of splashing the contents of the bottle. This object is attained by means of a novel combination and arrangement of parts to `be hereinafter described and claimed, reference being had to the accompanying drawing, in which- Figure l is a sectional view of the upper portion of the bottle provided with the improved closure; Fig. 2 is a plan view of a sheet of the sealing devices, and Fig. 3 isa plan view showing a modified form of seal ing device.

Referring speciically to the drawing, 5 denotes the neck of an ordinary milk bottle, the same containing an .annular shoulder or cap recess 6 positioned as usual aslight distance below the upper edge of the bottle neck. The closure is Ia paper cap 7 seating in the bottle neck on the shoulder 6, as usual.

ln order that the cap 7 may make a hermetic closure, and may also be readily removed, there is placed against the under side thereof, before it is applied to the bottle, a sheet 8 of flexible material, such asr paper, and preferably rectangular 1n outline to provide projecting tongues 9. The cap is placed at the center of the sheet, and the cap and the sheet are then pressed into the bottle neck, with the corners of the sheet, i

forming the tongue 9, projecting above the cap so that they may be grasped to remove the cap, this being readily effected as the sheet extends beneath the cap and the tongues project a suiiicient distance from the cap so that they are readily grasped.

rThe sheet 8 is larger than the cap 7 and it completely encircles the edge thereof and is jammed into the recess 6 when the cap is applied, thereby forming a vtight joint around the seat of the cap and eectually excluding air from the bottle. in order to make a better joint, that portion of the sheet which seals the joint has a circular series of short radial slits 10. rFhe slitted portion of the sheets adapts itself readily to lthe cap seat when pressed thereinto, the material at the slits overlapping. Without these slits the sheet is apt to fold or ruffle, which will not make a good seal.

The sheets'S may be of plain or waxed or paraffined paper, and they can be pasted on the cap or left loose. rlfhe sheets may be marketed by providing a single large sheet divided into individual sheets by lines of perforations similar to sheets of postage stamps. Fig. 2 shows such a sheet. 'llhe sheet 8 also has, midway between its corners, radial slits l1 extending to the slits 10, whereby the tongues 9 are separated.

Fig. 3 shows a slightly different shaped sheet 12, the same being elongated so that only its ends proj ect from the bottle neck to form the tongues whereby the cap 7 is removed.

'Fhe device is not limited to milk bottles but may, with equal facility, be applied to other bottles and jars.

l claim:

The combination with a bottle cap, of a sheet of fiexible material of greater size than the cap and having a series of radial slits, terminating at their outer ends short of the edges of the sheet said slitted portion of the sheet encircling the edge of the cap, and that portion of the sheet which is outside the slits extending outward from the edge of the4 cap.

ln testimony whereof ll aix my signature in presence of two witnesses.
